Home / How to measure current in a high-voltage busbar
The use of a current clamp or current transformer greatly simplifies measuring high currents (>50A) where physical constraints (conductor sizes, insertion losses, safety) make a direct measurement through the precision internal shunt of a power analyzer, DMM, or external shunt. This complete, busbar assembly reference design offers a non-invasive (isolated and lossless) current measurement solution up to ±100 A. Accurate measurement of busbar currents is essential for ensuring reliable operation, fault detection, and grid management. This paper proposes a non-contact current measurement method for three-phase rectangular busbars based on TMR (tunneling magneto-resistance) sensors, due to their advantages of large dynamic range, wide bandwidth, light weight, and easy installation.
